I bought a Jiayu g2f phone. After one week usage the WCDMA went wrong, util yesterday it was still good.
Now only possible to use the phone 2G in both slots. (GSM mode, max speed: EDGE) Other case: only emergency calls accepted...not able to join to 3G network.
I don't know why. If somebody know any fix please share with me. Possible to die the 3G module inside the phone or ...?
same problem

Hey guys. I was recently playing around with my girlfriend's Optimus One (from T-Mobile) and it doesn't get 3G signals at all. I think she gets edge, but that's as good as it's going to get. She has perfect wifi, but her device is unable to connect to 3G. I read that it operates with 2100 and 1700 bands, but I'm not sure what that entirely means and how to fix the problem. Any suggestions?
I bought a Chinese Clone of an HTC S720e and I cannot get it to "see" the ATT wireless network with my SIM card. Says Network Not Available. No voice calls, no signal, no data, no nothing.
Info is HDC G23i ONE X S720E 4.7'' Capacitive Screen 3G WCDMA MTK6575 1.8Ghz Dual Core Android 4.0.3 Dual sim 8MP WIFI GPS
Specs can be seen at http://www.fastcardtech.com/goods-7353-HDC+G23i+ONE+X+S720E+47+Capacitive+Screen+3G+WCDMA+MTK6575+18Ghz+Dual+Core+Android+403+Dual+sim+8MP+WIFI+GPS.html
It's supposed to be able to work on 900 and 1850 MHz like ATT needs.
I called ATT and got them to accept the IMEI that came with the phone. (It's actually one of those Dual SIM card phones).
I have tried a million different APN settings and nothing seems to work. The phone doesn't see any signal at all! Really makin me mad.
I tried a Star N8000 from China before and it had no problem working with my SIM card. Why can't this one?
Appreciate any suggestions.
Bump! Also I notice when I turn the phone off, it says "Restricted Access Changed"
Any soultion to this? I have the same problem connecting to Swedish network, Telia

Hi friend, i hope you can help me!
I bougth an Note5 F6, it´s a dual sim phone with 6" screen and Android ICS. In "Enginner Mode" and next BandMode option appears UMTS Mode, WCDMA-IMT-2000, WCDMA-PCS-1900. Does it means that phone works on this frecuencies? If so...why doesn´t phone detect any network? My my last phone does, but when i set sim card on Note5 not. I´m interested on 1900 3G network. Thanks!
and dorbso
Mmm nobody knows...
Hi guys,
Canvas HD is not working in USA. Tried AT&T SIM. Tried everything like changing the APN settings, but didn't quite work.
I read somewhere that it's a problem with the frequency bands, i.e., this phone supports 900/1800 and 3G HSDPA 2100; and AT&T has 2G 850/1900, I guess.
So, my question is: will my phone support this SIM or not? Any hack I could try?
*Really tensed right now, phone screen cracked too the day I landed*
*Bump*
Any thoughts?

it wont work...the gsm bands that canvas 3 supports are only 900/1800..usa needs 850/1900...and the 3 g band is 1700/2100 in usa...the canvas 3 is set to 2100...so the phone is gonna be useless.a piece of brick might be more useful.i had the same problem.i am still in usa.my canvas 3 is dead as a bat.wrote to the company..no real response...send it back if you can and next time buy a quad band..i learnt the hard way...
Hi,
I have bought a jiayu g4 basic phone, I'm having problems getting the 3G to work, I have an O2 sim in and a Vodafone sim in it, none of them will work on 3G, I have tried switching from one to the other in sim management but it will still not connect to the internet, 3G is enabled,
sorry if this post is in the wrong place but I couldn't find anywhere else to put it,
Please help, Chris
Jiayu G4 only works @ 2100 Mhz in WCDMA mode
Which frequency your carrier use for 3G?
